In reply to Stevie. Do you have a link to the study? I can't seem to find it...

This is interesting. But aren’t you missing a major visible light source between the sun and screens? Like lightbulbs? A 2017 study found that LED light caused darkened pigment in 80% of subjects at 60 J/cm^2 (incandescent light had no effect). There’s been a huge push to change lightbulbs to LEDs for energy efficiency. Office spaces are generally lit to 1.1 W/sqft, which is 0.00118 W/cm^2. To get to 60 J/cm^2, you’d have to spend 50,847 sec or 14 hours in that light. To get to your baseline of 40 J/cm^2, you’d only have to spend 9.4 hours in the office. Which is about how much time I spend in my office. Then I go home, and turn on my LED light bulbs XD

I’d love to hear your thoughts on this.

Interesting article Michelle.

I’d agree that Blue Light is probably harmless as far as our skin is concerned, but realistically, our eyes aren’t really adapted to handle the amount of Blue Light we “see” today.

I use a software called Iris to filter it out of my laptop screen – it works a charm!

Hi,
I love your blog, thanks for the info.
I have a question, does the screen light damages our eyes? and if so, is there a way to protect us?
I’ve heard about special glasses, but I have no idea 🙁

You are hands down my favourite beauty blogger of all time: with facts and scientific studies in place of all the nonsense.

Thank you for your time and effort to research this (and other) beauty issues and for sharing your findings with us, instead of keeping all your secrets to yourself. You’r the best!

What about blue led light therapy for acne? Is that the same type? Is that also bad!?

HI Michelle! Thanks so much for your informative content, I always learn so much from your posts and videos(: Would you please consider doing a segment debunking those LED light therapy face masks, as in whether they really work or just a scam? Thanks so much in advance!

Skinmedica came with a system called Lumivive. Basically it’s 2 serums, one for night and one for day. It’s designed to protect your skin against blue light. I would love trying them because of the ingredients, but the price is way to high.

What a public service you have provided here, I hope it can be more widely circulated. I have worried about the light exposure from devices for a long time, and am relieved at your conclusions. Thank you for doing the hard work to assess the various risks.
